Fifty seeds were selected at random from...

Fifty seeds were selected at random from each of 5 bags of seeds, and were kept under standardised conditions favourable to germination. After 20 days, the number of seeds which had germinated in each collection were counted and recorded as follow

To solve the problem, we need to calculate the probability of different scenarios based on the germination of seeds from the bags. We have the following data from the bags: - Bag 1: 40 seeds germinated - Bag 2: 48 seeds germinated - Bag 3: 42 seeds germinated - Bag 4: 39 seeds germinated - Bag 5: 41 seeds germinated ...

A polling agency recently surveyed 1,000 adults who were selected at random from alargecity and asked each of the adults,“Are you satisfied with the quality of air in the city?”Of those surveyed,78 percent responded that they were satisfied with the quality of air in the city. Based on the results of the survey, which of the following statements must be true? I. Of all adults in the city,78 percent are satisfied with the quality of air in the city. II. If another 1,000 adults selected at random from the city were surveyed,78 percent of them would report they are satisfied with the quality of air in the city. III. If 1,000adults selected at random from a differentcity were surveyed,78percent of them would report they are satisfied with the quality of air in the city

A research study was conducted to determine whether a certain electrical implant, I, is successful in improving hearing . From a large population of people with hearing loss, 400 participants were selected at random. Half were randomly selected to receive the implant and the other half did not receive the implant . The resulting data showed that people who received the implant had significantly improved hearing compared to those who did not receive the implant. Based on the study , which of the following is an appropriate conclusion ?

Three colonies of insects were each treated with a different pesticide over an 8-week period to test the effectiveness of the three pesticides. Colonies A, B, and C were treated with Pesticides A, B, and C, respectively. Each pesticide was applied every 2 weeks to one of the three colonies over the 8-week period. The bar graph above shows the insect counts for each of the three colonies 0, 2, 4, 6, and 8 weeks after the initial treatment. Of the following, which is closest to the ratio of the total number of insects in all three colonies in week 8 to the total number of insects at the time of initial treatment?

Study the given data and answer the questions that follow. A sample of an enzyme called lactase was isolated from the intestinal lining of a calf. Assays were undertaken to evaluate the activity of the enzyme sample. The substrate of lactase is the disaccharide lactose. Lactase breaks a lactose molecule in two, producing a glucose molecule and a galactose molecule. Two assays were carried out. {:("Lactose concentration (% w/v)",15,15,15,15,15,15),("Concentration of enzyme smaple (%v/v)",0,5,10,15,20,25),("Reaction rate "mu"mole glucose "sec^(-1)mL^(-1),0,25,50,75,100,125):} {:("Lactose concentration (% w/v)",0,5,10,15,25,30),("Concentration of enzyme smaple (%v/v)",5,5,5,5,5,5),("Reaction rate "mu"mole glucose "sec^(-1)mL^(-1),0,15,25,35,40,40):} What are the variables in each of the two assays ?
